... base excitation. Closed-form expressions for the optimal tuning of the auxiliary spring-mass system are found, and the results are presented for the cases of the attachment and node located at the same and different locations. The assumed modes method is used, so the results can be applied for...

... isolation frequency that can be tuned over a broad frequency range. The material properties and geometry of the F 2 MC element, as well as the port inertance, determine the isolation frequency. A unique feature of this device is that the port inertance depends on pressure so the isolation frequency can be...

...Giola B. Santoni; Lingyu Yu; Buli Xu; Victor Giurgiutiu An analytical and experimental investigation of the Lamb wave-mode tuning with piezoelectric wafer active sensors (PWASs) is presented. The analytical investigation assumes a PWAS transducer bonded to the upper surface of an isotropic flat...

... example of usual cases for which their exact solutions are not obtained by the well-known heuristic approach. In this paper, more natural formulation of this problem is studied, and algebraic closed-form exact solutions to both the optimum tuning ratio and the optimum damping coefficient for this classic...

...Nader Jalili, Mem. ASME, Assistant Professor Semi-active (SA) vibration-control systems are those which otherwise passively generated damping or spring forces are modulated according to a parameter tuning policy with only a small amount of control effort. SA units, as their name implies, fill the...
